Abstract
An earth formation traversed by a borehole is investigated. A borehole tool having a neutron source and a photon detector is located in the borehole and used to obtain photon scatter information in or about the borehole. A chemical element located in a region in or about the borehole is quantified by using the photon scatter information and at least two different spectral standards for that element.
